aegis-blue-team-detection SKILL.md skillC
aegis-blue-team-detection from as-foss/aegis-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Detection-engineering companion that converts every vulnerability class this playbook's red-team modules can find into mandatory log signals, alert thresholds, and purple-team-validated detections so defenders catch both exploitation attempts and successful compromises.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Blue-Team Detection Engineering (DETECT) ## Scope & Objectives Invert the red-team view of this playbook into blue-team instrumentation requirements. Every other check module proves a vulnerability CLASS is exploitable; this module defines what must be LOGGED and what must ALERT so defenders see exploitation attempts (probes, bursts, error noise) and successful compromises (state changes, egress touches, deny-then-allow flips) for each of those classes. Deliverables of an audit run with this module: 1. **Coverage matrix scorecard** — for each of the twelve classes (INJ, WEB, AUTHN, AUTHZ, SSRF, FILE, DESER, API, LOGIC, DOS, TOK, LLM), classify instrumentation as FULL / PARTIAL / BLIND using the matrix in Patterns & Signatures. 2. **Detection-rule catalog** — the concrete signals, log-line shapes, threshold starters, and false-positive pressures per class. 3. **Pipeline-flow verdict** — is the path app → log → shipper → store → alert → human intact, measured end to end. 4. **Purple-team validation record** — replay results proving each deployed detection actually fires (Exploitation & Reproduction). …

How to install
mdr add as-foss/aegis-skills/aegis-blue-team-detection@sha256:47b68a0ad405e35cThe line at the top of this page pins the label git:20260826.9702747, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
